4. REGISTER DEFINITIONS
The DS21349 contains eight registers for configuring the device and reading status. These are accessible
using the serial port. Table 4-A lists the register names and addresses.
Reading or writing to the internal registers requires writing one address/command byte prior to
transferring register data. The first bit written (LSb) of the address/command byte specifies whether the
access is a read (1) or a write (0). The next 6 bits identify the register address.
The last bit (MSb) of the address/command byte is the burst mode bit. When the burst bit is enabled (set
to 1) and a READ operation is performed, addresses 10h through 17h are read sequentially, starting at
address 10h. And when the burst bit is enabled and a WRITE operation is performed, addresses 10h
through 17h are written sequentially, starting at address 10h. Burst operation is stopped once address 17h
is read. All data transfers are initiated by driving the
CS input low. All data transfers are terminated if the
CS input transitions high. Port control logic is disabled and SDO is tri-stated when CS is high.
